  When disasters such as earthquakes and typhoons occur and damage to multiple cultural properties, prompt recovery is required. If rapid recovery is delayed, the risk of losing many cultural assets increases. For example, in the Hyogoken-Nanbu Earthquake, more than 1200 historical buildings were damaged, and it took more than 3 months to grasp the damage by human hands, and the emergency response was delayed or not in time. As a result, many cultural property buildings were lost. In addition to natural disasters such as earthquakes and typhoons, there is also a risk that cultural assets may be damaged or lost due to human disasters such as arson, theft or mischief. For example, over the past four years, 28 intrusions and thefts have occurred in important cultural property buildings (data at the end of 2005).

  Conventionally, as a countermeasure against such a problem, there is a security system of a security company using a fire alarm or an intrusion detection device installed on the outer periphery or outer wall of a cultural property. However, the conventional security system cannot grasp the current state of the cultural property and the progress of the state from the viewpoint of protecting the cultural property, and cannot use it for the occurrence of a problem. In addition, when a disaster occurs, there is a high possibility that the entire system will be stopped due to the disaster or data will be lost, and it will not play a role in protecting cultural assets and managing the state.

  In view of the above-described problems, the present invention grasps the current state of the cultural property or the surrounding environment of the cultural property and the progress of the state, and further manages the state of the cultural property so that data is not lost even if a disaster occurs. The problem is to provide a system.

In order to solve the above-described problems, the present invention provides a grid computing system having a server in charge of a cultural property that is one or more management targets, using a server installed on the management target using the server in charge. Analyzes and accumulates the acquired status data,
The server in charge was changed based on the amount of data or the contents of the status data.

  Specifically, the present invention is installed in a cultural property that is a management target, has a sensor that acquires state data of the cultural property or its surrounding environment, and a server in charge of one or more of the management targets, A grid computing system that is a virtualized computer using the responsible server as a computer resource, and the grid computing system is obtained by the sensor installed in the management target using the responsible server. Analyzing / accumulating means for analyzing and accumulating state data; and server-in-charge changing means for changing the server in charge of the management target based on the data amount or data content of the state data acquired by the sensor; It is a cultural property state management system.

  The management object of the cultural property state management system according to the present invention is not only historical buildings but also general cultural properties including arts such as paintings and sculptures and historical materials. Here, the state data acquired by the installed sensor is data indicating the state of the cultural property itself and the state of the surrounding environment surrounding the cultural property. The cultural property state management system according to the present invention analyzes and stores this state data by a grid computing system.

  A grid computing system is a system that provides services as a combined virtual computer by connecting computer resources on the Internet or a wide area network. The present invention distributes the state data by such a grid computing system, so that processing such as analysis and storage as a whole is continued even in the event of a disaster, and the accumulated data is not lost. It is possible to provide a state management system.

  Furthermore, the cultural property state management system according to the present invention has a server-in-charge changing means, and is in charge of the management target based on the change in the data amount or data content of the state data. The server in charge can be changed as appropriate according to the load applied to the processing.

  The responsible server changing means, in any one of the management targets, when the data amount of the state data acquired by the sensor installed in the management target exceeds a predetermined amount or the data content has a predetermined threshold value In the event that the number exceeds, the server in charge of the management target may be a dedicated server used for analyzing and storing the status data related to the management target.

  Here, the predetermined amount is a data amount that is set in advance or is dynamically set as an index for measuring the load applied to the server in charge during processing, and the predetermined threshold is acquired. In order to determine whether or not an event that is different from normal, such as the occurrence of a disaster, has occurred in the managed cultural property or its surrounding environment The threshold value to be set.

  According to the present invention, the server in charge in charge of a plurality of management targets is usually a dedicated server in charge of only one management target, so that an increase in the load described above or an event different from the normal time can be obtained. It becomes possible to cope with the occurrence.

  The grid computing system uses the server in charge to analyze the state data acquired by the sensor, thereby calculating a soundness calculation means that calculates a soundness that is an index indicating the degree of deterioration of the management target And a soundness storage means for storing the soundness calculated by the soundness calculation means as a database using the server in charge.

  Further, the sensor acquires speed or acceleration as the state data, and the soundness level calculation means performs eigenvalue analysis or modal analysis based on the speed or acceleration acquired by the sensor, and the soundness of the management target The degree may be calculated.

  By calculating and accumulating the soundness level, it is possible to always grasp the degree of deterioration of the cultural property that is the management target. In other words, it is possible to take quick and accurate cultural property protection measures, such as taking emergency measures in descending order of deterioration and high urgency.

  The cultural property state management system further includes an exciter that excites the management target, and the soundness calculation means analyzes the speed or acceleration acquired by the sensor during the excitation by the exciter, The degree of soundness of the management target may be calculated.

  The speed or acceleration used to calculate the soundness level may be obtained by measuring normal microtremors, etc., but it is further equipped with a vibrator, and vibrations artificially generated by this vibrator are obtained by a sensor. Thus, in addition to the analysis based on the microtremor, more appropriate data can be acquired and used for the analysis.

  The cultural property state management system is an observation point information processing apparatus installed for each of the one or more management targets, and stores the state data acquired by the sensor and transmits the state data to the grid computing system You may further provide a point information processing apparatus.

  Even if communication with the grid computing system is cut off in the event of an emergency such as a disaster by storing data in the observation point information processing apparatus installed for each of the one or more management targets, the observation point information processing apparatus The accumulated data can be collected and the data can be recovered.

  The sensor may be a sensor that has been subjected to incombustibility treatment.

  By setting the sensor to be a non-combustible sensor, the sensor can also be used for cultural assets such as wooden cultural assets that could not be installed due to the risk of fire. It is possible to install and monitor the condition.

  By the present invention, it is possible to grasp the current state of the cultural property or the surrounding environment of the cultural property and the progress of the state, and further provide a cultural property state management system that does not stop even if a disaster occurs and does not lose data. It becomes possible.

  An embodiment of a cultural property state management system according to the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an outline of a state in which various sensors are installed on the management target 1 in the present embodiment. In this embodiment, a Buddhist temple 1A and a Buddha image 1B installed in the Buddhist temple 1A will be described as an example of the management object 1 such as a cultural property. In the management target 1, various sensors such as a temperature sensor 11, a humidity sensor 12, a CCD camera 13, a triaxial acceleration sensor 14, a triaxial angular velocity sensor 15, an ultraviolet sensor 16, a moisture detection sensor 17, and a water level sensor 18 are installed. . These various sensors are connected to an observation point information processing apparatus 30 installed for each one or a plurality of management objects 1.

  The temperature sensor 11 and the humidity sensor 12 measure the temperature and humidity inside and outside the cultural property, and transmit the measurement data to the observation point information processing device 30. The CCD camera 13 shoots the inside and outside of the cultural property and the state of the cultural property such as the Buddha image 1B, and transmits the captured moving image or still image to the observation point information processing device 30. The triaxial acceleration sensor 14 and the triaxial angular velocity sensor 15 measure the movement (vibration, rotation angle, etc.) of the installed cultural property, and transmit the measurement data to the observation point information processing device 30. In this embodiment, an acceleration sensor is used to measure the movement of the cultural property. However, a speed sensor may be used instead of the acceleration sensor. In addition, the moisture detection sensor 17 and the water level sensor 18 measure the moisture and the water level inside and outside the cultural property, and transmit the measurement data to the observation point information processing device 30. Other installed sensors transmit measurement data acquired by the sensor to the observation point information processing apparatus 30.

  In order to prevent fire, non-flammable technology is used for the various sensors. More specifically, flame retardant glass, epoxy, etc. are used for the printed circuit boards of the electronic circuits of various sensors and the observation point information processing device 30, self-extinguishing materials are used for parts, etc., and wiring materials are used. Use heat-resistant electric wires that have been irradiated with an accelerated electron beam.

  The power supply circuit that supplies electricity to the various sensors and the observation point information processing device 30 includes, for example, 1) an overvoltage protection device (when an overvoltage occurs due to an erroneous operation or an accident, the circuit protector for the power switch is shut off instantaneously. 2) Overheat protection circuit (The power switch is shut off when the temperature of the main components inside the equipment exceeds the specified level.) 3) Surge absorber (Protects the circuit from surge voltage generated in the power line due to lightning strikes, etc.) 4) Reverse connection prevention circuit (protects the circuit when reverse polarity voltage is applied to the output terminal) 5) Short circuit prevention circuit (protects the circuit when the output terminal is short-circuited), 6) Excessive Protective measures such as a current detection circuit (the output current is constantly monitored and protected from overcurrent) are taken.

  In addition, the observation point information processing apparatus 30 that receives information from various sensors is preferably installed outside the cultural property that is the management target 1 in order to prevent fire. Furthermore, it is preferable that the power source of the observation point information processing device 30 is a battery power source or a solar power source so that the operation is not stopped in the event of a disaster. However, the power supply by battery power supply or solar power generation may be a standby power supply at the time of disaster, and operating power may be obtained from a normal power network (for example, via an AC100V adapter) during normal times.

  FIG. 2 is a diagram showing a configuration of the observation point information processing apparatus 30 in the present embodiment. The observation point information processing apparatus 30 includes an analog filter 32a, an AD converter 31, a digital filter 32d, a central processing unit 33, a main storage device 34, a clock 35, a communication unit 36, an interface 37, and an auxiliary storage device 38. The analog filter 32a mainly removes electrical noise in the signal from the sensor. When the measurement data output from various sensors is an analog signal, the AD converter 31 converts this into a digital signal. The digital filter 32d removes unnecessary components in the converted signal. The central processing unit 33 controls the observation point information processing device 30 as a whole in accordance with a program developed in the main storage device 34 and the like. The main storage device 34 temporarily stores data. The clock 35 provides a clock to the central processing unit 33. The communication unit 36 communicates with the grid computing system using a wireless or wired communication means. Further, the auxiliary storage device 38 locally stores information obtained from various sensors.

The observation point information processing apparatus 30 accumulates information obtained from various sensors in the auxiliary storage device 38, and simultaneously transmits information to the grid computing system using communication means such as wireless or wired communication. Information transmission is mediated by relay servers, routers, wireless communication relays, and the like. For example, when the management target 1 is in a place that is not suitable for laying a wired line, or when considering the possibility that the wired line is disconnected at the time of a disaster, information transmission via a wireless line is preferable. However, since there are radio-specific problems such as radio interference in wireless communication, the communication method should be appropriately selected in consideration of the environment around the management target 1 and the like. In addition, by accumulating data in the observation point information processing device 30, even when communication with the grid computing system is cut off in an emergency such as a disaster, the data accumulated in the observation point information processing device 30 is collected, Data can be recovered.

  Next, an outline of the grid computing system in the present embodiment will be described. FIG. 3 is a diagram showing an outline of the grid computing system in the present embodiment. A grid computing system is a system that provides services as a combined virtual computer by connecting computer resources on the Internet or a wide area network.

  The grid computing system according to the present embodiment includes calculation / data servers 2 (corresponding to servers in charge of the present invention) distributed on the Internet or a wide area network, and these calculation / data servers 2 are computers. This is a grid computing system that operates as a single virtual computer having a high-speed and large-capacity disk as a resource and a high-speed arithmetic processing capability. Further, in this embodiment, in order to make computer resources distributed in various places into virtual computers, programming middleware based on Grid RPC (Grid-enabled Remote Procedure Call) is used and distributed to various places by remote procedure call. Using the functions of the arranged calculation / data server 2 and the like, the entire system is a virtual computer having high-speed computing capability.

  The calculation / data server 2 receives data generated by various sensors via the observation point information processing device 30, and performs various calculations (analysis of measurement data, etc.) instructed by the administrator terminal / user terminal 3. Further, it is an apparatus for accumulating in an auxiliary storage device etc. of the calculation / data server 2. At this time, various calculations and accumulations may be processed by one calculation / data server 2 or may be distributedly processed by a plurality of calculation / data servers 2.

  More specifically, the calculation / data server 2 analyzes the measurement data measured by the temperature sensor 11 and the CCD camera 13 to detect a fire, or the measurement data measured by the moisture detection sensor 17 and the water level sensor 18. Is detected to detect the occurrence of water damage, and based on the information obtained by the triaxial acceleration sensor 14 and the triaxial angular velocity sensor 15, typhoons and earthquakes are detected. Further, the measurement data measured by the humidity sensor 12 is analyzed to calculate the risk of deterioration due to the occurrence of mold and high / low humidity, and the measurement data by the ultraviolet sensor 16 is analyzed to manage by ultraviolet rays. The risk of deterioration of the target 1 is calculated. Furthermore, for a cultural property that is to be managed 1 other than a building, such as a Buddhist image 1B in the Buddhist temple 1A, theft or the like occurs based on information obtained from the triaxial acceleration sensor 14 or information obtained from the CCD camera 13. And detect intruders.

  The administrator terminal / user terminal 3 is a device mainly for a user to make settings and instructions to the grid computing system. Here, the administrator terminal / user terminal 3 may serve as a computer resource for computation or storage in the grid computing system.

  Further, as described above, the observation point information processing apparatus 30 accumulates information obtained from various sensors in the auxiliary storage device 38, and simultaneously transmits information to the grid computing system using communication means such as wireless or wired communication. . Here, the observation point information processing apparatus 30 may serve as a computer resource for calculation or accumulation in the grid computing system.

<Management target assignment process>
The calculation / data server 2 is usually in charge of a plurality of management objects 1, and analyzes and accumulates data generated in the sensors installed in each management object 1 in charge. For this reason, the number of calculation / data servers 2 is set smaller than the number of management objects 1. For example, the calculation / data server 2A is in charge of the management objects 1a, 1c, and the calculation / data server 2B is in charge of the management objects 1b, 1d, 1e (see FIG. 3).

  Here, when the management target 1 is attacked by a disaster such as a typhoon and the data amount is increased due to a narrow data sampling interval in various sensors, the load of the calculation / data server 2 in charge of the management target 1 is increased. Increase the number of calculation / data servers 2 in charge, make the calculation / data server 2 in charge a dedicated server, or take charge if there is a risk that the nearby calculation / data server 2 may be down due to damage. The calculation / data server 2 is changed to a remote calculation / data server 2.

  For example, when the management target 1b is attacked by a typhoon, the calculation / data server 2A is in charge of the management targets 1a, 1c, 1d, and 1e, and the calculation / data server 2B is in charge of only the management target 1b. You may make changes in charge. This change in charge may be performed in response to an instruction from the administrator terminal / user terminal 3 or may be autonomously performed by the servers connected to the grid computing system communicating with each other. Good.

  Here, the assigned server change process is performed by the grid computing system in accordance with, for example, the algorithm shown in FIG. That is, the processing shown in the following flowchart may be performed by any one of the calculation / data servers 2 or may be distributed by a plurality of computer resources constituting the grid computing system.

  In step S101, acceleration data and water level data are read. The grid computing system reads measurement data from the three-axis acceleration sensor 14 and the water level sensor 18 installed in any observation target as processing target data. Thereafter, the process proceeds to step S102.

  In step S102, it is determined whether either the acceleration or the water level has exceeded a threshold value. The grid computing system refers to the threshold value set in advance by the administrator terminal / user terminal 3 and compares either the acceleration data or the water level data read in step S101 with either acceleration data or water level data. It is determined whether or not this threshold is exceeded. If it is determined that the threshold value is exceeded, the process proceeds to step S103. If it is determined that the threshold value is not exceeded, the process proceeds to step S105.

  In step S103, the calculation / data server 2 in charge is changed. The grid computing system selects the calculation / data server 2 in charge of the observation target in which the three-axis acceleration sensor 14 or the water level sensor 18 that has acquired the measurement data determined to exceed the threshold value in step S102 is installed, The distribution of the calculation / data server 2 in charge of each observation target is changed. At this time, the grid computing system may select a plurality of calculation / data servers 2 as the calculation / data server 2 to be changed, or select only one calculation / data server, and use this server as a dedicated server. It is good. Further, the distance from the observation target may be taken into consideration as a reference for selection. For example, if the disaster is local, it is possible to avoid being damaged at the same time by taking charge of the remote calculation / data server 2. Thereafter, the process proceeds to step S104.

In step S104, analysis / storage processing is started in the changed calculation / data server 2. The grid computing system starts analysis / storage processing of measurement data measured by the various sensors installed on the observation target, using the computer resource of the calculation / data server 2 of the change destination changed in step S103. . Thereafter, the processing shown in this flowchart ends.

  In step S105, the normal calculation / analysis processing in the data server 2 is continued. The grid computing system continues the analysis / storage processing of the measurement data by various sensors using the computer resources of the calculation / data server 2 that is in charge of the observation target at the normal time. Thereafter, the processing shown in this flowchart ends.

  In the process of changing the assigned server shown in this flowchart, the content of the measurement data is referred to and the determination is made based on the threshold (see step S102). However, the data amount of the measurement data is referred to by referring to the data amount of the measurement data. It may be determined whether or not a predetermined amount is exceeded. By making judgments with reference to the amount of data, it is possible to distribute the processing load or concentrate on a dedicated server even when the amount of data acquired by various sensors during a disaster increases. is there.

  According to the present embodiment, the calculation on the system is not subject to time restrictions and geographical restrictions by the grid computing system that is distributed over a wide area (for example, all over Japan) in order to manage a plurality of management objects 1. The correspondence relationship between the data server 2 and the management target 1 can be changed. In addition, by making it possible to change the correspondence relationship, it becomes possible to cope with a disconnection of a system line or an operation stop of each server in an unexpected situation such as a disaster.

  In addition, the cultural property management grid computing system according to the present embodiment is used to prevent theft and mischief. Usually, the measurement data measured by the three-axis acceleration sensor 14 attached to the Buddha image 1B or the cultural property is stored in a data server and becomes a database for deterioration diagnosis or the like. However, if the measurement data measured by the three-axis acceleration sensor 14 exceeds a preset acceleration due to mischief or movement, an alarm is issued or a report is sent to the security company. To prevent.

  Specifically, the grid computing system performs processing according to the algorithm shown in FIG. That is, the processing shown in the following flowchart may be performed by any one of the calculation / data servers 2 or may be distributed by a plurality of computer resources constituting the grid computing system.

  In step S201, acceleration data is read. The grid computing system reads measurement data from the water level sensor 18 installed in any observation target as the processing target data. Thereafter, the process proceeds to step S202.

  In step S202, it is determined whether or not the acceleration exceeds a threshold value. The grid computing system refers to the threshold value set in advance by the administrator terminal / user terminal 3 and compares the acceleration data read in step S201 with respect to whether or not the acceleration data exceeds this threshold value. judge. If it is determined that the threshold value is exceeded, the process proceeds to step S203. If it is determined that the threshold is not exceeded, the process proceeds to step S204.

  In step S203, an alarm is issued and a report is made to the security company. The grid computing system issues an alarm in response to the determination result in step S202. Specifically, an instruction is issued to cause the observation point information processing device 30 or the like to turn on an alarm lamp or generate an alarm sound. In addition, the grid computing system reports to a security company via a network. Thereafter, the processing shown in this flowchart ends.

  In step S204, normal analysis / accumulation processing is continued. The grid computing system continues the analysis / storage processing of the measurement data by various sensors using the computer resources of the calculation / data server 2 that is in charge of the observation target at the normal time. Thereafter, the processing shown in this flowchart ends.

  The various sensors are preferably sensors having a function of receiving commands via the system and changing the type and amount of data to be observed. By using a sensor having such a function, the administrator terminal / user terminal 3 controls the sensors via the grid computing system, or the calculation / data server 2 autonomously transmits the sensor. It is possible to obtain the data necessary for the analysis by controlling the sensors according to the instruction.

<Health level / risk level grasp processing>
Next, the soundness / risk level grasping process of the management target 1 using the three-axis acceleration sensor 14 will be described. FIG. 6 is a diagram showing a system configuration for performing soundness / risk level grasping processing in the present embodiment. The cultural property state management system according to the present embodiment periodically excites with the vibrator 20 provided in the cultural property such as the five-storied pagoda 1C, analyzes the measurement data by the three-axis acceleration sensor 14, and the cultural property. To understand the health / risk of

  As a method for grasping the soundness / risk of a cultural property, there is eigenvalue analysis or modal analysis. In eigenvalue analysis, for example, a power spectrum or the like is calculated from data measured by the three-axis acceleration sensor 14 using a grid computing system, and changes in eigenvalues (for example, eigenvalues decrease when a cultural property is damaged and rigidity decreases) are observed. It is a method to do. Further, the modal analysis is a method for grasping the behavior and amplitude of the cultural property with the grid computing system based on the measurement data obtained by the triaxial acceleration sensor 14. There is also a method of grasping the degree of soundness / risk by using fine movement without using the vibrator 20 by using the highly sensitive three-axis acceleration sensor 14.

  The soundness level / risk level analyzed by the above-described soundness level / risk level measurement process is databased on the grid computing system for each management target 1. This database is constantly updated, and the progress of deterioration for each management target 1 is recorded.

  Moreover, the structural characteristics of the management target 1 may be input and set in advance. For example, by inputting into the database information such as the weight of the roof due to restoration and the details of the seismic reinforcement work, the rating of the degree of risk (ease of collapse) at the time of disaster is stored on the database. As a result, when a part of the grid computing system is damaged due to a disaster, it is possible to preferentially monitor the management target 1 with the higher risk rating when grasping the damage in real time when an actual disaster occurs. It is.

  By performing the above-mentioned soundness / risk level grasp processing, the damage degree of each cultural property building and historical heritage is grasped in real time, and first aid is taken in descending order of damage from the most serious. It is possible to take quick and accurate cultural property protection measures.

  According to the cultural property state management system according to the present embodiment, by using a grid computing system, computers scattered in various places can perform calculation processing even during a large-scale disaster such as an earthquake, a typhoon, or a flood. Since the data is stored, unlike the computer system of the security company, it is possible to provide a cultural property state management system that is less likely to become impossible.
